Kinematic Equations - Manipulating them.

Huynher

Hi, I'm new to this forum.

I need major help on my homework. So the kinematic equation,
Vf² = Vi² + 2ad

I need to figure out how to manipulate it so I can find Vf(final velocity), Vi(initial velocity), a(acceleration), and d(displacement).

I figured to find Vf, you just square root it, but I can't figure out how to get everything else.

Vi = ?
a = ?
d = ?

Any help will be greatly appreciated. Thanks.

It's simple algebra, really...

Vf² = Vi² + 2ad
Vf² - 2ad = Vi²
Then square root both sides of the equation, and voila! I'm sure you can figure out a and d for yourself...
